I was having a issue for virtualenv and was trying to make a environment ,my terminal was showing

zsh: command not found: virtualenv

and so I looked for a article about this issue and it said to do this command

and I got allot of error issues,

sudo /usr/bin/easy_install virtualenv

I decided to make a environment and see what happens

I use 3.10.0 but over here in the error I think it tried to install to version 2.7

I did

pip3 uninstall virtualenv

pip3 install virtualenv

, and tried to make a new environment. Still the same error occurs. I think I messed up 2.7. What should I do?! I am using MacOS if it helps

From the directory structure I assume that you are using macOS. You could install virtualenv using Homebrew (see here), or using pip, Python's package manager. — bool3max

Please install Python3. Don't install pip into Python2 because it will not work. Also, sudo is never a correct solution to this problem — OneCricketeer

So it was not possible to do virtualenv environment But python3 -m venv environment I am not sure why it is like this but once I ran the command it seems that it made it into a environment

These are two different things

Yes they are two different things. While virtualenv supports older Python versions, venv is actually the preferred way (excluding other distributions like conda) to create an environment.

zsh: command not found: virtualenv

sudo is not a fix for this. Figuring out what is wrong with the current user's PATH, is the solution here...

However, Python3 comes with venv rather than needing to install anything else

python3 -m venv my-env
source my-env/bin/activate
